I Application filed Ia 81, 1928, Serial 110.- 281,782, and in Aultria July 14, 1987.

This invention relates to water glide shoes in which during use the foot or leg is readily removably connected with a float, which comprises a skeleton covered with a water- 5 tight envelope or coat.

According to the present invention the envelope or coat together with atubular extension, serving for the insertion and watertight packing of the foot and preferably extending to near the knee, consists of a single member or of a numberof parts which are permanently united to a unit, the skeleton being inserted into thesaid envelope or coat by way of the tubular extension and is stretched out and braced up in the interior thereof. a

Compared with other water glide shoes in which a skeleton, consisting of a number of parts which are screwed together, is covered with a watertight envelope or coat in the manner of acollapsible boat, the water glide shoe according. to. the present invention possesses the feature of g1 eat lightness and great stability, caused in that the individual parts of the skeleton, which is fitted togethei in the interior of the tubular or baggy closed envelopeor coat,are propped up or stiffened with respect to each other and the envelope or coat, so that they may be ofver small dimensions and do not require. to e interconnected.

Therefore. a pair of this kind ofwater glideshoes, WhlCh weigh approximately 1 3 ounds, can be comfortably carried in a knapsack and fitted together within a few minutes without the aid of any means which may belost, while the known water glide 'shoes weight aboutul l poundsand a large number of screws or the like arenecessary for fitting up theskeleton.

Owingto the small weight of'the water glide shoes it is possible to lift the legs and to step' over, similar as it is the case when skiing. wherebyit is also possible to readily get up after having fallen in the water.

One mode of carrying: out the present invention is illustrated by way of example on the accompanying sheet of drawings in which a 1 a Figs. 1, 2 and show the water glide shoe in side view, plan view and front view respectively; i s a i Figs; and 5 illustrate the two parts of the skeleton. i p Fig. 6 is a perspective view of the connecting member of the skeleton-bars 'velope.

Fig. 7 illustrates the stiffening frame and the mode of arranging the bars.

Fig. 8 shows on an enlarged scalethe mode of connecting the bars. Figs; 9,10 and 11 are detail views.

The glide shoe is formed by a float memher, which encloses the foot or leg removably connected with it and is completely closed with the exception of. the opening for inserting the foot or leg (Figs. 1 and 2). The

float consists of a skeleton of wooden or metal bars or rods 11 or the like, which is fitted 1n thepreferably baggy or tubular envelope, 1) of a watertight material. The envelope is completely and permanently closed with the exception of the o ening 0 (Fig 2) for inserting the foot an the parts of the skeleton. The latter consists of two groups of bars or the same being retained by a sleeve 3 (FigsL 4, 5 and'6). Theconnecting members 1 of the groups of bars a and a form the ends of the glide shoe, which brace up or stiffen the bars with respect to the'ends of the en- The bars a of the skeleton are supported by transverse frames 4, held. apart and premed against the envelopeas well as secured the correct distance from one another.

Every frame ,4 is provided'with grooves 5,

for thearrangement of the bars a (Fig. 7). At corresponding places, the bars are furnished withnotches or groovesfiyvhich are adapted to coincide with the grooyes of the frames 4 (Fig. 10), so that the bars a of theskeletonalternately embrace the frames at the bearing places and are inunovablysecured in position" by the tension of theen velope. v

. Also the oppositely disposed bars a of the two groups of bars are braced up with respect to one-another by the tension of the envelope and are connected with each other by means of sleeves 7 In order to produce the necessary strain, the ends 8 of the bars a are chan'lfered and a wedge 9 is passed through an opening of the sleeve 7 and disposed between the same, the envelope 1) of the glide shoe bearing against the said wedge 9 and secures the same in its position.

A plate or board 11 (Fig. 7), to which is a attached the means for securing the foot, is detachably connected by means of rotatable hooks or the like with the two frames 4, which are disposed at the sides of the opening 0 and serve for the support of the skelethe opening a of the float, so that the means for securing the foot can be quickly disengaged 'by pulling on the'string18.

The string 18 is preferably connected with the closing belt, which serves for water-' tightly securing the tubular extension of the 7' envelope to the leg, so that by opening this belt also the rear bracket or belt 13 is automatically disengaged and thus the connection between the foot or leg and the glide shoes is completely interrupted.

. The finor pocket shaped extensions 71 of the envelope 1) of the float are formed by swinging flaps 19 (Fig. 11) which are braced u by wire-insertions and are connected to i the envelope 1) of the float by means of ears 20 of a liable material, so that the flaps 19 can easi y fold down and again stand up, and in the collapsed condition and the dismantled condition of the shoe take up very little s ace,

In t e dismantled condition the ghde shoes can be carried in a bag or the 11ke, be-

cause they take upvery little room. The glide shoes are fitted up very quickly w1thout screw-connections and without the use other transverse frames 4 are of tools, this being carried out in the following manner The envelope b is unfolded, the two groups of bars 8 and 8 8.113 fitted up by i serting the converging ends of the bars in the grooves 2 0f the connecting member 1 and securing the same in position by the sleeves 3. The transverse frame 4, which is to be arranged near the end, is pushed between t-he'bars (Fig. 4), and now the oups of bars 8 and s are inserted into t e envelope b by way of the opening 0, the roup of bars a being disposed in the forwar part of the envelope and the group of bars 8 1n the rear portion thereof. Thereafter the ushed between the bars of the groups 0 bars and force apart the same towards the envelope 6. The oppositely disposed ends of the bars are connected by the sleeves 7 and are braced u against the two ends ofv the shoe by means of the wedges 8 (Figs. 7 and 8). Finally the means for securing the foot is inserted and fixed, and the glide shoes are fready for use.
